Thinking about running 6 PSI your thoght on stock enternals ECU tuning?

 

it is my understanding that you have to have a piggyback for the ECU to run forced induction.

 

f it Ill just get some headers and exhuast with the intake and call it a day

 

how much does a dyno tune cost?

 

Anyone know what kind of gains be expected on a 3.0 v6 with a c.a.i. and cat back system, upon install of headers? I am probably going to go n/a and just get a bottle. Maybe have the compression ratio changed and heads pollished.

 

it is my understanding that changing from the exhaust manifolds to headers makes a BIG difference with the RTs..
